  [1] Cost is the total cost incurred for the direct, physical interconnection of generators that started commercial operation in the respective years.  These generator-specific costs may include costs for transmission or distribution lines, transformers, protective devices, substations, switching stations and other equipment necessary for interconnection.
  Notes: See Glossary reference for definitions. Totals may not equal sum of components because of independent rounding.
